        Correct, and after clear crash and install srs module to car, we have this DTC B1655:00-0A - FRONT BUCKLE SWITCH RH FAILURE. So look is like program wrong clear or work with flash. And that with any srs modules for Subaru with locked RH850

          All active errors must be fixed on car.
          Here is a step-by-step solution to fix this problem Subaru Crosstrek Service Manual - Dtc b1655 front buckle switch rh failure - Diagnostic procedure with diagnostic trouble code (dtc)

            Hi, I have the same codes on a 2024 Subaru Crosstreck 98221fn22a, And with 2021 Subaru Outback 98221an01c . First I thought it was the buckle switch or the wiring issue but it was bad comptures. I think is bad clear. I put different computers and the codes went away.

              Try to make "Zero point calibration" in "Ocupant Detection" system.
              Or check and fix all errors before clearing the crash data.
